Given numbers are 470, 155, 575, 891

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(470, 155) = 14570

GCD(470, 155) = ( 470 x 155 ) / 14570

= 470 / 155

= 470

Step2:

LCM(5, 575) = 575

GCD(5, 575) = ( 5 x 575 ) / 575

= 5 / 575

= 5

Step3:

LCM(5, 891) = 4455

GCD(5, 891) = ( 5 x 891 ) / 4455

= 5 / 891

= 5

So, Greatest Common Divisor of 470, 155, 575, 891 is 1
